DC3-MFP-85WA-K
MECO
The DC3-MFP-85WA-K is a slim-profile ceiling concealed duct fan coil unit designed for installations where vertical ceiling space is constrained. With a body thickness of 200mm, this unit fits into narrow ceiling cavities while delivering conditioned air through ductwork. It belongs to the K-Series slim duct FCU lineup, which covers air volumes ranging from 510 to 1360 m³/h across different model variants.
The unit features a low-profile rectangular casing built for horizontal ceiling mounting. The left and right water pipe connections are field-reversible, allowing installation flexibility on-site. An air return box is included as standard, with multiple return air style options available to match project requirements. The condensate drain pan is integrated into the unit base, and a condensate drain pump can be added as an optional accessory for applications where gravity drainage is not feasible.
This fan coil unit uses plastic centrifugal fan wheels to reduce operational noise. The heat exchanger is constructed with copper tubes and hydrophilic aluminum fins, which facilitates heat transfer and moisture removal. Both EC and DC motor configurations are available as options, allowing specifiers to select the motor type that aligns with their control system requirements and energy efficiency targets.

This slim duct fan coil unit is suitable for commercial and residential buildings with limited ceiling plenum depth. Common applications include hotel guest rooms, office spaces, residential apartments, hospital wards, and small retail units. The concealed installation preserves interior ceiling aesthetics, while the ducted configuration allows for distributed air delivery through multiple supply registers.
Several options are available to adapt the unit to specific project requirements. EC/DC brushless motors can be specified in place of standard AC motors for variable-speed control and reduced energy consumption. A condensate lift pump is available as a factory- or field-installed option. The return air box style can be customized to match ductwork layouts. Both two-pipe and four-pipe system configurations are supported across the K-Series product range.
Sufficient service access should be provided at the unit end where water connections and the electrical box are located. The reversible water connection design accommodates both left-hand and right-hand piping layouts. The unit must be mounted level to ensure proper condensate drainage. When using the 30 Pa high-static configuration, ductwork design should account for the available external static pressure to achieve rated airflow.
The plastic fan wheels and drain pan should be inspected periodically to prevent dust accumulation and microbial growth. Air filters, where installed, require regular cleaning or replacement according to site conditions. Coil surfaces should be kept free of debris to maintain heat transfer performance. Motor bearings are permanently lubricated and do not require periodic re-greasing under normal operating conditions.
The unit body measures 200mm in thickness. Installers should allow additional clearance for duct connections, insulation, and the condensate drain line. A minimum plenum depth of approximately 250mm is recommended for standard installations.
Yes. The fan coil unit supports both two-pipe and four-pipe hydronic systems. In two-pipe configurations, the unit operates in either cooling or heating mode depending on the water supply temperature. Four-pipe setups allow simultaneous heating and cooling capability with separate coil circuits.
DC and EC motor options support external speed control signals, enabling integration with building automation and energy management systems. Control interface specifications should be confirmed at the time of order to match project control protocols.
